Abstract: A fuser belt for a reproduction machine is disclosed. The belt may have one of several configurations which all include ridges and interstices on the outer surface which contacts the print media. These interstices are formed between regularly spaced ridges, between randomly spaced particles, between knit threads. These interstices allow the free escape of steam from the media during high-temperature fusing of the reproduction process. As the steam escapes freely, the steam does not accumulate in the media causing media deformations and copy quality deterioration. Additionally, media handling is improved because the ridges and interstices reduce the unwanted but unavoidable introduction of thermal energy into the copy media.

Abstract: The invention relates to a high voltage AC power supply which can be operated as either a constant current source with overvoltage protection or as a constant voltage source with current limiting protection. The power supply includes a sinusoidal transformer having a high turn winding and a sampling circuit on its secondary side for sampling voltage proportional to the load current. A comparator compares the sampled voltage to a reference voltage and supplies an error voltage to a buck regulator. The buck regulator converts the error voltage to a variable DC voltage which is fed to an oscillator formed by the primary winding of the transformer.

Abstract: A feed mechanism for a photocopy or similar machine directs the media, particularly wide-format media, into a receiving tray along a path which is substantially parallel to, but in the opposite direction of, the original media path. This allows for the removal of media from the front of the photocopy machine. With the drive mechanism in a first configuration, the leading edge of the media is fed directly into the receiving tray. Responsive to a position of the leading edge of the media, the drive mechanism changes to a second configuration so that the subsequent portion of the media is allowed to form a loop and to be delivered to a second receiving area.

Abstract: A cartridge dispenser for dispensing toner through the use of a plurality of baffles positioned within the cartridge which serve to collect a prescribed amount of toner and dispense it during different strokes of oscillation of the cartridge.

Abstract: A bar lens assembly for a reproduction machine is provided. The assembly includes a stiffening member provided with a mounting pin to which a bar lens array is mounted. The lens array is precisely located with respect to the mounting pin. A method for assembling the bar lens assembly is also disclosed wherein locating bushing is positioned over a mounting pin of a lens array mounting place and the lens array is provided with an opening through which the locating pin passes. The lens array is affixed to the mounting plate and thereafter the locating bushing is removed. The lens array is thereby precisely positioned with respect to the mounting plate.
